I can reproduce the error and confirm your analysis.

It's hard to answer the question: that regexp has been there for more
than 20 years now ;-)

I don't have the time to do it now (I also have a flaky Internet
connection in this period), but if someone wants to tackle this issue,
I fixed something similar for \addbibresource a few months ago:

    * b2f69e18 (2017-03-31)  Fix detection of bibliography files with
    dots in path

Please, also add a test.  Maybe this could be an occasion to review
similar regexps (for \include, \bibliography, etc), or maybe have a
common variable for all this cases.

Bye,
Mosè
